Frequency of ABO/Rhesus (D) blood groupings and ethnic distribution in the Greater-Accra region of Ghana, towards effective blood bank inventory.

Knowledge on blood group phenotypes is of key importance in clinical practice. It used in blood transfusion practice to determine the direction of recruitment of voluntary donors as required for each population within a country, and for disease association and population genetics studies. This study aimed at reporting the frequency of ABO and Rhesus (Rh) groups in the population of the Greater-Accra region of Ghana and amongst their various ethnic groups.

Folate status of Ghanaian populations in London and Accra.

Migration to the UK is associated with higher incidence of stroke in African populations. A low folate status has been associated with increased risk of stroke, likely to be mediated through raised plasma homocysteine concentrations. We conducted a cross-sectional study to compare blood folate and homocysteine concentrations in eighty healthy Ghanaian migrants living in London matched by sex, age and occupation to 160 individuals from an urban population in Accra, Ghana.
